ABSTRACT:
The front of a camera lens mount, provided with a photocell window adjacent the objective, can be fitted with a light shield closely surrounding the cone of incident light rays and cutting across the photocell axis. To insure proper illumination of the photocell, a light conductor extends alongside the light shield from the vicinity of the photocell window to about the plane of the inlet end of the light shield.
